An improved power supply for the AN/PRC-117G military radio has been developed. The presently disclosed power supply includes an ac-dc power conversion module; a dc-DC power module and an onboard battery backup. The disclosed power supply is an adaptable power supply which configures to provide ac-dc power; dc only power and battery backup power. The ac and dc power modules are independent and separable, and may be configured by the radio user to remove the ac module and operate in a dc only mode. The adaptability of the power supply includes universal power supply for the Harris Corporation Falcon III series of radios which includes the AN/PRC-117G; RF-7800H-MP; RF-7800M-MP; RF-7800-RC; AN/PRC-160 and the RF-7800-RT intelligence, surveillance and reconnaissance terminal.

The U.S. military employs a type of radio transceiver known as the AN/PRC-117G. The AN/PRC-117G is used in line of sight, and non-line of sight modes and can be carried by an individual, mounted in vehicles or mounted at a fixed sight. The AN/PRC-117G's design includes several related radios which use the same specifications for power input these radios include the RF-7800H-MP; RF-7800M-MP; RF-7800-RC; AN/PRC-160 and the RF-7800-RT intelligence, surveillance and reconnaissance terminal. These radios are manufactured by Harris Corporation and are widely used within the U.S. military for commonality between air, ground and naval forces. In the manpack mode the AN/PRC-117G is attached to a portable lithium battery which provides the radio's power. The lithium battery has a fixed life measured in hours and must be replaced. When used in a vehicle, aircraft, vessel or fixed installation the AN/PRC-117G and related radios use a power supply which is also known as a battery eliminator. The power supply eliminates the need for the manpack battery and can use global AC or DC power and convert the power to the correct voltage and current for the radio. Currently, existing AN/PRC-117G power supplies are manufactured as a unitary design. This design provides an AC conversion function integrated into the design and the AC conversion module is not separable from the DC conversion function. In applications such as vehicles, aircraft and vessels where the AC conversion function is not needed the current power supply is inseparable from the functionality. Existing AN/PRC-117G power supply designs have fixed cable connections which limit installation and design. The cable connectors on existing designs are on one side of the power supply and are fixed. For installations where cable connections are made from the opposite side installation requires complex cable routing and connections and increases strain on both the cables and the connectors.
In some aspects, the invention relates to an AC-DC power supply for the AN/PRC-117G radio by providing DC output power for the radio by converting either AC or DC input power into useable power by the radio. Said power supply supports the AN/PRC-117G radio by removing the battery pack and attaching the power supply, also known as a battery eliminator. The said power supply is a modular power supply with modules separable and distinct and includes a first power module which receives AC input and converts AC power to DC power. A second power module receives DC input and converts the DC input to DC output suitable for the AN/PRC-117G radio. An onboard battery backup provides backup power when both external AC and DC power is lost.
In some aspects, the invention relates to an uninterruptable power supply by taking either AC or DC power input and charging the onboard battery pack and providing automatic switchover to battery backup when external power is lost.
In some aspects the invention relates to a DC power supply by removing the AC power conversion module and using the power supply in a DC only configuration.
In some aspects the invention relates to an power supply adapter comprising a removable and replaceable modular adapter which allows use with the Falcon III based series of radios including the RF-7800H-MP; RF-7800M-MP; RF-7800-RC; AN/PRC-160 and the RF-7800-RT intelligence, surveillance and reconnaissance terminal.
It should be noted that identical features in different drawings are shown with the same reference numeral. Left side or right side is depicted as the user would be looking at the front of the radio with power supply.

Circuit boards contained within the first DC module, 2, and the first AC module 3, provide the power conversion and charging capability of the power supply. The first DC module 2, and the first AC module 3, may be used together, as depicted in
While the invention is shown in several embodiments, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modification without departing from the spirit thereof. For example, the adapter module, 1, allows installation of other adapter configuration to affix to radios with like power requirements including the RF-7800H-MP; RF-7800M-MP; RF-7800-RC; AN/PRC-160 and the RF-7800-RT intelligence, surveillance and reconnaissance terminal. Additionally, the power and current output specifications can easily be varied to accommodate radios with different power requirements.
